0:01:08 > 0:01:09Hello, everyone!
0:01:09 > 0:01:12ALL: Hello, Nina!
0:01:12 > 0:01:15- Ready for an experiment?- Yes!
0:01:15 > 0:01:18It's a tasty experiment today.
0:01:18 > 0:01:21We're going to be making... instant ice cream!
0:01:21 > 0:01:25Now, what do I need? Hmm, that's right.
0:01:25 > 0:01:27Spoon - got it.
0:01:27 > 0:01:30Big bowl for the ice cream - excellent.
0:01:30 > 0:01:32All the ingredients are here.
0:01:32 > 0:01:35So we need some cream.
0:01:37 > 0:01:39Ohhhh!
0:01:39 > 0:01:40Beautiful.
0:01:40 > 0:01:43That should be plenty.
0:01:43 > 0:01:44Some sugar as well.
0:01:44 > 0:01:46Not too much sugar.
0:01:46 > 0:01:48That should be enough.
0:01:48 > 0:01:50Lovely.
0:01:50 > 0:01:53And a few drops of vanilla flavour
0:01:53 > 0:01:56cos vanilla ice cream's my favourite.
0:01:58 > 0:02:01Perfect! Lovely.
0:02:01 > 0:02:04Now all we need to do is freeze it, but quickly.
0:02:04 > 0:02:07For that, we need something very cold.
0:02:07 > 0:02:11Luckily in my lab, I always have very cold liquid nitrogen.
0:02:11 > 0:02:12Excellent!
0:02:12 > 0:02:15I just need to pop my protective gloves on.
0:02:17 > 0:02:19Take the canister off.
0:02:19 > 0:02:21BUBBLING
0:02:21 > 0:02:24Can you hear that? That's it bubbling away.
0:02:29 > 0:02:32I think I'll put two scoops in.
0:02:33 > 0:02:37NINA LAUGHS
0:02:41 > 0:02:44I feel like a with with a cauldron!
0:02:44 > 0:02:47Do you know, I think it's ready.
0:02:47 > 0:02:49Look at that!
0:02:49 > 0:02:52All the liquid nitrogen has bubbled off
0:02:52 > 0:02:55and it's left only the ice cream.
0:02:55 > 0:02:57It looks good enough to eat
0:02:57 > 0:02:58and I think I will!
0:03:04 > 0:03:07Mmm! Mmm, that is delicious!
0:03:09 > 0:03:12Thank you very much, everyone!
0:03:12 > 0:03:14Have a lovely day. Bye!
0:03:14 > 0:03:18- BEEPING - I hear a beep, I see a flash.
0:03:18 > 0:03:21I wonder what they're going to ask.
0:03:28 > 0:03:29Hi Nina, I'm Joe.
0:03:29 > 0:03:32How can I stop my snowman from melting?
0:03:32 > 0:03:36My goodness! A snowman melts quickly if it gets hot
0:03:36 > 0:03:38so this is an emergency.
0:03:38 > 0:03:41- Thanks, Nina.- Bye!
0:03:41 > 0:03:44We'll need some help to answer this one
0:03:44 > 0:03:46and I know just who to ask.
0:03:46 > 0:03:49OK, Neurons, time to get to work.
0:04:03 > 0:04:06ALL: Neurons at the ready, Nina!
0:04:06 > 0:04:08OK, guys.
0:04:08 > 0:04:12Today's question is how can I stop my snowman from melting?
0:04:12 > 0:04:15Which Neuron can help us find the answer?
0:04:15 > 0:04:19ALL: Me! Me! Me! Me! Me!
0:04:19 > 0:04:22Will it be fabulous Felix?
0:04:22 > 0:04:25I can help so very much if you need the sense of touch.
0:04:25 > 0:04:27Will it be beautiful Belle?
0:04:27 > 0:04:30I send messages brain to ear.
0:04:30 > 0:04:32If there's a sound, I'll help you hear.
0:04:32 > 0:04:34Will it be lovely Luke?
0:04:34 > 0:04:36Looking and seeing, day or night,
0:04:36 > 0:04:39I'll help you with your sense of sight.
0:04:39 > 0:04:41Will it be awesome Ollie?
0:04:41 > 0:04:44If it's pongy or whiffy or you can't tell,
0:04:44 > 0:04:46my messages help your sense of smell.
0:04:46 > 0:04:47Or Baby Bud?
0:04:47 > 0:04:49Sour, salty, bitter or sweet,
0:04:49 > 0:04:52I'm your taste buddy whenever you eat.
0:04:52 > 0:04:54BEEPING
0:04:56 > 0:04:58- It's Felix! - CHEERING
0:04:58 > 0:05:01ALL: Go, Felix! Go, Felix!
0:05:01 > 0:05:03Go, Felix! Go, Felix!
0:05:03 > 0:05:05Go, Felix! Go, Felix!
0:05:05 > 0:05:07Go, Felix!
0:05:07 > 0:05:11Marvellous! A little touch can mean so much, Nina.
0:05:11 > 0:05:15We're going to find out about things that feel hot and cold
0:05:15 > 0:05:17so Felix is the Neuron to help us out
0:05:17 > 0:05:21so we'd better get a move on! There's not a moment to lose.
0:05:23 > 0:05:27OK then, let's go!
0:05:51 > 0:05:55Meet Joe, his mum and his friends Georgie and Lucas.
0:05:55 > 0:05:57They live in Andorra
0:05:57 > 0:06:00but today for one day only,
0:06:00 > 0:06:04they are...The Experimenters!
0:06:07 > 0:06:10Hi, everyone! Hi!
0:06:10 > 0:06:11You must be Joe.
0:06:11 > 0:06:15You wanted to know how to stop your snowman from melting.
0:06:15 > 0:06:18So, how is your snowman?
0:06:18 > 0:06:20- There.- Oh!
0:06:20 > 0:06:22Oh dear, is that him?
0:06:22 > 0:06:25What exactly are we meant to be looking at?
0:06:25 > 0:06:29Oh no! Poor snowman!
0:06:29 > 0:06:34Ah, it used to be a snowman, but now it's melted.
0:06:34 > 0:06:40With two lumps of coal for his eyes and the carrot was his nose!
0:06:40 > 0:06:43Aw! Don't cry, Bud.
0:06:43 > 0:06:46They can always build another snowman.
0:06:46 > 0:06:48He doesn't look very well, does he?
0:06:48 > 0:06:53Although there's snow around, it's too warm for snowmen today.
0:06:53 > 0:06:57Unless we can come up with a plan to make him last longer!
0:06:57 > 0:07:01We need to do an experiment and Felix is ready to help us out.
0:07:01 > 0:07:02Aren't you, Felix?
0:07:02 > 0:07:05BEEPING
0:07:07 > 0:07:10- Ready, Felix? - Oh, it's my big moment!
0:07:10 > 0:07:14Standing by, ready to send lots of messages.
0:07:14 > 0:07:17So, first thing's first -
0:07:17 > 0:07:21Joe, can you tell me what is a snowman made of?
0:07:21 > 0:07:23Hmmm...snow.
0:07:23 > 0:07:25Correct!
0:07:25 > 0:07:29And there's loads of snow down here so follow me.
0:07:32 > 0:07:36Here I have got two snowballs, exactly the same size.
0:07:36 > 0:07:38We're nearly ready to start.
0:07:38 > 0:07:42Have you guys ever played a game called pass the parcel?
0:07:42 > 0:07:45- Yes.- It's one of my favourite games.
0:07:45 > 0:07:49This is called pass the snowball. Cool name, eh?
0:07:49 > 0:07:52Do you get it? "Cool" name? Snowball?
0:07:52 > 0:07:57Never mind. First of all, we'll play it with our gloves off.
0:07:57 > 0:08:00I'll put one down. Are you ready?
0:08:00 > 0:08:01- Yes.- Pass the snowball!
0:08:01 > 0:08:05Oh, Nina, it's going to get cold on your hands.
0:08:05 > 0:08:08Don't be silly, Felix, it looks like fun!
0:08:08 > 0:08:13I guess so. It is part of the experiment, after all.
0:08:13 > 0:08:16Oh! Look, look what's happening.
0:08:16 > 0:08:20- What's happening? - It's melting. It's getting smaller.
0:08:20 > 0:08:23That's right, it's getting smaller.
0:08:23 > 0:08:25Any ideas why it's melting?
0:08:25 > 0:08:26Cos you hands are warm.
0:08:26 > 0:08:31The warmth of our hands is making the snowball smaller.
0:08:31 > 0:08:33So how do our hands feel?
0:08:33 > 0:08:34Cold!
0:08:34 > 0:08:36Mine are very cold as well
0:08:36 > 0:08:40so it's time for the other half of our experiment
0:08:40 > 0:08:43and it's the same but with our gloves ON.
0:08:43 > 0:08:45Ready, Felix?
0:08:45 > 0:08:49Yes indeed! Felix is ready to feel and touch.
0:08:50 > 0:08:52Ready with your gloves on?
0:08:52 > 0:08:54And...go!
0:09:08 > 0:09:12BEEPING
0:09:12 > 0:09:14Oh, last time round.
0:09:20 > 0:09:23Oh! Now, how does this snowball look?
0:09:23 > 0:09:28- The same.- That's right, it's a lot bigger than the last one.
0:09:28 > 0:09:30I wonder why that is.
0:09:30 > 0:09:32- Cos of our gloves.- That's right.
0:09:32 > 0:09:34That's exactly right.
0:09:34 > 0:09:38Wearing gloves stops the snowball from melting so quickly.
0:09:38 > 0:09:41If our gloves can stop a snowball from melting,
0:09:41 > 0:09:45maybe clothes could stop a snowman from melting.
0:09:45 > 0:09:48- Let's go and build a snowman! - THEY CHEER
0:09:48 > 0:09:51Remember the gloves, Nina!
0:09:51 > 0:09:53The snow is so cold to touch.
0:09:53 > 0:09:55I'm on a snowball watch,
0:09:55 > 0:09:58- just in case anyone throws one at Nina.- Good idea!
0:09:58 > 0:10:00That can hurt sometimes.
0:10:15 > 0:10:19BEEPING
0:10:36 > 0:10:40Oh, that's him dressed.
0:10:40 > 0:10:44There's one more thing that'll make him a real snowman.
0:10:44 > 0:10:47- A carrot for his nose!- That's right.
0:10:47 > 0:10:52A carrot is for eating AND for making noses with!
0:10:52 > 0:10:55It makes a perfect nose for the snowman.
0:10:55 > 0:10:57Would you look at that!
0:10:57 > 0:11:01Perfect! I can tell he's gonna last a long, long time.
0:11:01 > 0:11:04Why don't we go sledging and come back later
0:11:04 > 0:11:06to see if he's still here?
0:11:06 > 0:11:08- Yeah!- Excellent!
0:11:40 > 0:11:43Hi! Aaaaaaah!
0:11:45 > 0:11:49While others are sledging, we can look at our snowman.
0:11:49 > 0:11:53He's not melted away at all. Fantastic!
0:11:53 > 0:11:56That answers a question as well.
0:11:56 > 0:11:59Your question was how can I stop my snowman from melting?
0:11:59 > 0:12:03First, we found out that snow starts to melt
0:12:03 > 0:12:06when it's touched with warm things like our hands.
0:12:06 > 0:12:11By keeping our gloves on, we helped keep the snowball frozen.
0:12:11 > 0:12:15Next we discovered, with the help of our lovely snowman,
0:12:15 > 0:12:19that if we cover his body with a jacket and with a scarf,
0:12:19 > 0:12:22it kept him cooler for longer
0:12:22 > 0:12:24and it helps stop him from melting.
0:12:24 > 0:12:28Our sense of touch has been well exercised today!
0:12:28 > 0:12:31I better be off and you'd better go back sledging.
0:12:31 > 0:12:33Let's go. Bye, Mr Snowman!
0:12:47 > 0:12:50# It's been a busy, busy day
0:12:50 > 0:12:53# Questions, answers Experiments done
0:12:53 > 0:12:56# We've all used our senses in so many ways
0:12:56 > 0:12:59# Tell me, Neurons What have you done today? #
0:12:59 > 0:13:03Well, I definitely worked the hardest today.
0:13:03 > 0:13:06Feeling all that cold - brrr!
0:13:06 > 0:13:11And then touching the snowball and feeling it melt on Nina's hand.
0:13:11 > 0:13:13Yeah, I was pretty busy.
0:13:13 > 0:13:16There was so much to see.
0:13:16 > 0:13:18All the shapes of the snowball
0:13:18 > 0:13:21and how they changed shape when they melted.
0:13:21 > 0:13:24There were loads of sounds to keep me busy.
0:13:24 > 0:13:28All the shrieks and giggles when the snowman was being made.
0:13:28 > 0:13:32I loved the sound of the crunchy snow.
0:13:32 > 0:13:35We've had a bit of an easy day, haven't we, Bud?
0:13:35 > 0:13:39Yeah, but I've still had a fabby time!
0:13:47 > 0:13:49That was great fun.
0:13:49 > 0:13:52Hope you've had a sensational time too. Bye!
0:13:52 > 0:13:54ALL: Bye!
